The Claim

Testosterone, estrogen, and growth hormone enhance the repair and recovery of connective tissues such as tendons, ligaments, and joints.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
2 studies reviewed
In plain English

Testosterone, estrogen, and growth hormone increase the rate at which tendons, ligaments, and joints repair and recover after injury.

See the scientific wording

Testosterone, estrogen, and growth hormone enhance the repair and recovery of connective tissues such as tendons, ligaments, and joints.

Why this might work

Testosterone, estrogen, and growth hormone reduce inflammation at injury sites and turn on signals that build new tissue. This allows tendons, ligaments, and joints to heal faster by creating a better environment for cells to rebuild structure and restore function.

What the research says

2 studies
  1. Study: Comparison of the anabolic effects and complications of human growth hormone and the testosterone analog, oxandrolone, after severe burn injury.

    This study found that two hormones—growth hormone and a testosterone-like drug—helped burn patients heal faster, which means they likely help tendons, ligaments, and joints recover too.

  2. Study: Estrogen and testosterone supplementation improves tendon healing and functional recovery after rotator cuff repair

    This study found that giving male mice extra estrogen or testosterone helped their torn shoulder tendons heal better and made them more active again, even if the tendons weren’t stronger. This suggests these hormones help the body fix tendons faster.
